Privacy Policy
Contextberg is a Windows desktop application developed and operated by an individual. The app automatically records your work time and uses AI to analyze your productivity.
By its nature, Contextberg handles privacy-sensitive data such as keyboard input and screen captures. This policy explains what we collect, why we collect it, and how we use it.
1. Data We Collect
All data collected by Contextberg is used to understand “what you were working on today.” Collection for each feature begins only after your explicit consent is obtained on the consent screen shown at first launch. Data for features you have not consented to will not be collected. You can also disable each feature individually from the Settings screen at any time.
Collected data is never sent outside your PC, except when the AI analysis feature is enabled. The timing and conditions under which data is sent externally are explained in detail in “3. AI Features.”
When AI analysis is enabled, all sensitive data categories below may be sent to Google’s AI service (Gemini) for analysis. See “3. AI Features” for details.
Application Usage
Records which apps you used and for how long — for example, “used VS Code for 2 hours” or “used Slack for 30 minutes.” This is the core function of Contextberg and forms the basis for all activity reports.
Keyboard Input (Sensitive)
Records what you typed in which app. This enables analysis such as “spent 1 hour coding” or “wrote an email.” Collected input text is not used for any purpose other than productivity analysis. It is not sold to third parties or used for advertising.
Screen Captures (Sensitive)
Automatically takes snapshots of your screen every few minutes. Used to visually review your work and to help AI understand your work context. Captured images are stored on your PC and automatically deleted after 30 days.
Clipboard Content (Sensitive)
Records text copied via copy operations. Used to help AI more accurately understand the work context during that time period. Can be disabled from the Settings screen.
Browser History (Sensitive)
Reads browsing history from Microsoft Edge and Google Chrome. Used to include web research and reference work in the activity log and to help AI understand the work context. Contextberg accesses the history files saved on your PC in read-only mode. It never modifies or writes to your browser settings or data. Can be disabled from the Settings screen.
2. AI Features
Work data is sent to an external AI service only when the AI analysis feature is enabled. Sensitive data is never sent to external servers for any purpose other than AI analysis.
When AI features are turned on, the previous hour’s work data (used apps, keyboard input, screen captures, clipboard content, browser history) is sent to Google’s AI service (Gemini) once per hour, and an activity report is automatically generated. Data is also sent when you manually generate a report from the AI chat screen.
Data transmission goes through Contextberg’s relay server (AWS). This server only temporarily relays data and does not permanently store your work content.
If you select “Local LLM (LM Studio)” in settings, all processing is completed on your PC, and no data is ever sent to external services.
Your data is never used to train AI models. Contextberg uses the Gemini API with settings that exclude your data from model training. Your work content is used solely to generate your individual analysis reports and is not retained by Google for training purposes.
To disable AI analysis, turn off the AI analysis feature from the Settings screen.
3. Data Sharing
The following are the parties with whom Contextberg shares your data. We do not sell or provide your data to any other third parties.
- Google (Gemini API) — Used to analyze work data only when the AI analysis feature is enabled. When enabled, data may be sent to servers located outside Japan. Google’s privacy policy applies.
- Stripe — Used to process payments for paid plans. Credit card information is managed by Stripe and is not stored on Contextberg’s servers.
4. Security & Data Management
Authentication credentials stored on your PC are protected by Windows’ standard encryption and cannot be accessed by other users on the same PC. All communications between Contextberg and external services are encrypted with HTTPS.
Most recorded data can be deleted from the Settings screen. For data not accessible through Settings (e.g. database files, log files), you can directly delete Contextberg’s data folder via Windows Explorer.
5. Policy Changes
If this policy is changed, a new version will be posted on this page. For significant changes, we will notify you within the app or by email.
